The prostate is both an accessory gland of the male reproductive system and a muscle driven mechanical switch between urination and ejaculation. It is found only in some mammals. It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the bladder, with the urethra passing through it. It is described in gross anatomy as consisting of lobes, and in Artery: Internal pudendal artery, inferior vesical artery,, Prostata (Vorsteherdrüse) Die Prostata ist ein pyramidenförmiges Organ mit Apex (Übergang in die Harnröhre) und Basis (Übergang in die Harnblase), welches unterhalb der Harnblase vor dem Rektum lokalisiert ist.

Huggins published studies in which he used estrogen to oppose testosterone production in men with metastatic prostate cancer.
GnRH receptor agonists, such as leuprorelin and goserelin , were subsequently developed and used to treat prostate cancer. External beam radiotherapy became more popular as stronger X-ray radiation sources became available in the middle of the 20th century. Brachytherapy with implanted seeds for prostate cancer was first described in The initial regimen of cyclophosphamide and 5-fluorouracil was quickly joined by multiple regimens using a host of other systemic chemotherapy drugs.
The prostate is found only in mammals. The structure of the prostate varies, ranging from tubuloalveolar as in humans to branched tubular. The gland is particularly well developed in dogs, foxes and boars, though in other mammals, such as bulls, it can be small and inconspicuous. They excrete this fluid along with their urine to mark their territory. The prostate gland originates with tissues in the urethral wall.
This means the urethra , a compressible tube used for urination, runs through the middle of the prostate. This leads to an evolutionary design fault for some mammals, including human males. The prostate is prone to infection and enlargement later in life, constricting the urethra so urinating becomes slow and painful. Prostatic secretions vary among species.
They are generally composed of simple sugars and are often slightly alkaline. Because the Skene’s gland and the male prostate act similarly by secreting prostate-specific antigen PSA , which is an ejaculate protein produced in males, and of prostate-specific acid phosphatase , the Skene’s glands is sometimes referred to as the „female prostate”.
